BOlLER-CLEANER.

SPECIFICATION forming part of Letters Patent No. 710,843, dated October7, 1902.

(No model.)

To all whom, it may concern.-

Be it known that I, JOHN W. OoNE,a citizen of the United States, and aresident of Barnesboro, in the county of Cambria and State ofPennsylvania, have invented a new and Improved Boiler-Cleaner, of whichthe following is a full, clear, and exact description.

My invention relates to improvements in boiler-cleaners; and the objectthat I have in View is the provision of a simple and efcientconstruction adapted to blow off impurities at the surface of the Waterin the boiler and to discharge sediment at different portions along thelength of the boiler at the bottoni thereof.

The improved cleaning device may be easily supplied to a boiler at a lowcost, and it is provided with valve devices adapted to control theoperation of eliminating the sediment at the bottom of the boilerthrough a series of successive collecting tubes or branches.

With these ends in view the invention consists in the construction,arrangement, and combination of parts, which will be hereinafterdescribed, and the actual scope of the invention will be defined by theclaims.

Reference is to be had to the'accompanying drawings, forming a part ofthis specication, in which similar'characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional elevation of an ordinary steam-boiler,illustrating my improved cleaner devices applied thereto, the plane ofthe section being indicated by the dotted line 1 1 of Fig. 2. Fig. 2 isa vertical transverse section in the plane of the dotted line 2 2 ofFig. 1. Fig. 3 is an enlarged sectional elevation through the collectingand discharging devices, parts of said devices being broken away; andFig. 4 is a vertical cross-section on the line 4 4 of Fig. 3.

In Figs. 1 and 2, 5 indicates an ordinary boiler having the steam-dome 6and the series of dre-tubes 7; but the boiler may be of any preferredconstruction. In the lower part of the boiler, preferably below theseries of nre-tubes 7 therein, is a horizontal discharge pipe or tube 3.This pipe or tube lies quite close t0 the bottom of the boiler at theplace where the sediment is liable to collect, and the said dischargetube or pipe extends longitudinally of the boiler, preferably from oneend thereof to and through the other end. The extended or projected endof this pipe or tube may be joined to one headof the boiler by anysuitable water-pipe connection, (not shown,) and said extended end ofthe tube is carried through the masonry-wall 9 or the boiler-front, asindicated more clearly by Fig. 3. The discharge tube or pipe is providedat points along its length with a series of collecting branches 10, thesame depending from the lower side of said pipe or tube 8 and curved, asshown by Figs. 2 and 4, so as to terminate in open mouths in thevertical plane of said tube 8. The curved collecting branches 10 'litvery closely to the bottom of the boiler, as shown by Figs. 1 and 2, and

these branches are thus adapted to extend into the sediment whichcollects at the bottom, this making provision for the thorough removalof thesediment from the lower part of the boiler.

The inner end of the tube or pipe Sis shown by Fig. 3 as having a head11, which serves to close said end of the pipe; but the outer projectingend of the tube which is carried through the wall or lfront 9 isprovided'with a depending discharge-leg l2 and with a stuifing-box 13 ofany suitable construction. This dischargeleg is disposed in an inclinedposition to the length of the tube or pipe 8, and any sediment whichaccumulates in the pipe is adapted to pass through this leg.

In order to control the passage or escape of the foul matter from theboiler, I employ a valve 14 of any suitable construction, said valvebeing adapted to open or close the inclined discharge-leg 12.

15 designates a valve-tube, which is snugly iitted within the dischargepipe or tube S and is adapted to be shifted therein by moving thevalve-tube endwise or turning it on its axis. The valve-tube is providedwith a series of ports 16, which are placed at variable distancestherein and in diiierent positions, so as to register individually withdifferent collecting branches 10, and with a verticallyextending tube,which Will be hereinafter doscribed. The valve-tube l5 is furthermoreprovided at one end with a skeletonized head or spider 17, the latterbeing made fast to the IOO tube in any suitable way. From this spiderextends a spindle 18, which passes through the stuffing-box 13 at theouter end of the discharge tube or pipe, and on this spindle is secureda hand-wheel 19, adapted to provide a convenient means for the operationof the valve-tube.

20 designates an upstanding pipe, which is provided with an elbow 21 atits lower end, the latter being secured to the discharge pipe or tube 8at a point between two of the co1- lecting branches 10 thereof. Theupstanding pipe 2O terminates in a horizontal branch 22, which isadapted to lie at the level of the water in the boiler, and the end ofthis branch 2 is open, so that any iloating refuse on the surface of thewater will easily pass into the tube 22 and the pipe 20, so as to bedischarged from the pipe or tube 8 and its branch 12 when the valve 14is open.

In the service of my improved boiler-cleaner the tube 15 is adjusted bythe stem 18 and the hand-wheel 19, so as to bring one of its ports 16into registration with the lower end of the upstanding pipe 20, which isfastened to the discharge-pipe 8. This adjustment of the valve-tubeallows the surface refuse to easily escape through the pipes 22, 21, 8,and 15 when the valve 14 is open in the dischargeleg 12. If it isdesired to remove sediment from the bottom portion of the boiler, thevalve 14 being closed the hand-wheel 18 is to be manipulated, so as toturn the valve-tube 15 or to shift it lengthwise within thedischarge-tube 8. This operation brings one of the ports 16 intoregistration with one of the collecting branches 10, and the sediment atone particular place on the bottom of the boiler is free to pass throughthe branch 10 into the tube 15 through the spider 17 thereof, and thencemake its exit by the inclined leg 12, the valve 14 being of course open.The valve-tube 15 may be again adjusted, so as to bring another of itsports 16 into registration with another of the collecting branches 10,and this makes provision for the discharge of the sediment from adifferent portion of the boiler. This ope ration may be continued untilall the branches 10 shall have been brought into service, and thus thesediment along the entire length of the boiler may be removed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A boiler-cleaner provided with a discharge pipelocated longitudinally in the lower part of a boiler and provided with aseries of inlet branches and with exteriorlylocated discharging means,and a valve-tube snugly fitted within said discharge-pipe and shiftableendwise and axially therein, said valve-tube having openings arranged tobe brought into registration individually with the inlet branches by anendwise or axial adjustment of said valve-tube.

2. A boiler-cleaner provided with a discharge pipe having an exteriorlylocated valve-leg, and a suitable stuliing-box which is located in theplane of said pipe, a series of inlet branches extending from the pipeand communicating with the passage therein, a valve-tube tted withinsaid pipe and having a series of inlet-ports, and a stem which passesthrough said stuffing-box, and a suitable handle attached to the stemand adapted to be manipulated to adjust the valve-tube by moving itendwise or axially within the discharge-pipe.

3. A boiler-cleaner comprising a dischargetube having a series ofdepending curved branches, and a single valve-tube which is adjustableand shiftable within said discharge-tube and is adapted to establishcommunication between said individual branches and said discharge-tube.

4. A boiler-cleaner provided with a discharge-pipe having a series ofdepending inlet branches and an upstanding pipe which terminates in ahorizontally-opening mouth at or near the Water-line of the boiler, avalvetube fitted within said pipe and provided with individual openingsarranged to be brought into registration with either of said dependinglbranches or with the upstanding pipe, and means for adjusting thevalve-tube endwise or axially within the discharge-pipe.

5. A boiler-cleaner, comprising a dischargetube having at its exposedend a stuffing-box and a valved discharge-leg, a series of dependingcollecting branches spaced at intervals along said discharge-tube, anupstanding collecting branch also attached to the discharge-tube, avalve-tube shiftably and adjustably fitted within said discharge-tubeand provided with ports arranged to individually communicate with saidcollecting branches, and a stem passing through the stuing-box andunited tothe valve-tube,sub stantially as speciied.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
